Research On The Key Problems In The Supplier Management Of Trunk Liner Program

Trunk liner is composed of millions of parts. It is a typical complex product. Its developmenthas large technical difficulty, long development cycle and huge financial input. So it is neccesaryfor the development of trunk liner to get the sufficient support from suppliers. The first flight ofBoeing787delayed several times because of the suppliers. So supplier management is veryimportant to develop a trunk liner. Main manufacturer-supplier mode is applied in the trunk linerprogram C919for the first time. Supplier management of the trunk liner program C919should beresearched. The paper focused on the key problems of the supplier management, and studied thefollowing problems.(1) The paper designed the frame of supplier management system of trunk liner program tosolve the key problems based on the supplier management flow and the fact of the CommercialAircraft Corporation of China Ltd.(2) The paper studied the text of supplier contract of BA corporation, summarized the type ofsupplier contract of BA, analyzed the character of the content of supplier contract of BA, andresearched the features of the contract management of BA. The contract of Boeing gives somegood ideas about the design of supplier contract of trunk liner program. To satify the need of trunkliner program, a standard supplier contract is estalished.(3) According to the features of the trunk liner program, the supplier selection model based onthe quality function house is crated to describe the logic procedure of supplier selection; and thenonlinear programming model is built to select the supplier.（4）Because of the uncertainty of the R&D, the effort of the suppliers has an important effecton it. So the main manufacturer will arrange the effort of each supplier through its special andpowerful position. This paper analyzed the influence of the efforts of suppliers on the benefits ofthe supply chain by applying Nash Equilibrium and Shapley Value. The results show that thecoordination by main manufacturer can improve the benefits of the whole supply chain. And thereasonable distribution of the benefits can increase the profit of each supplier and mainmanufacturer so that each supplier will be more active in the supply chain.(5) The paper presents a control model to slove the problem of supplier’s order allocation inmanufacturer-supplier model’s situation. After building mathematical model and getting transferfunction of each production processes through Laplace transform, simulation of the model inSimulink of MATLAB was implemented. And the results showed the feasibility and effectiveness of the model.(6) The risks from suppliers are relative. The maximum entropy model of the probabilitydistribution of the supplier risks in trunk liner program is created. The result is valuable for riskmanagement of trunk liner program.(7) A new multi-attribute intelligent grey target decision model is put forward in this paper.And the new model is applied to evaluate the performance of supplier. And the result shows theperformance of the suppiers are good now.
